Arianna,由于中国在4.29-5.3将会有端午节，为了避免您的航班由于节日延误，我们强烈建议您尽快催促会计付尾款，以便我们能尽快发出货物。如有什么问题请随时告知。请以此内容写一封英文邮件给客户Arianna.

Dear Arianna, I hope this email finds you well. I am writing to remind you that the Dragon Boat Festival will take place in China from April 29th to May 3rd. In order to avoid any potential delays caused by the holiday, we strongly recommend that you urge your accountant to make the final payment as soon as possible so that we can ship out the goods promptly. If you have any questions or concerns, please do not hesitate to let us know. We are always here to assist you. Thank you for your cooperation and understanding. Best regards, [Your Name]
